The PR expert agreed to join Bloomberg after quitting her Westminster job

How is the former Tory aide linked to Boris Johnson?

The pair have never confirmed any romantic ties between them, but sources suggest that they enjoy a very intimate relationship.

Rumours started when Symonds reportedly attended private dinner dates and political functions with the former Foreign Secretary, with the pair allegedly texting at all hours of the day and night.

Eyebrows were also raised at a colleague’s wedding when Symonds allegedly waved her mobile phone cheerfully showing mischievous text messages from Boris, who was then still serving as Foreign Secretary.

When did Boris Johnson announce his divorce?

The pair said in a joint statement that they separated "some time ago" and are now in the process of getting a divorce after 25 years of marriage.

In a statement they suggested their split was amicable, saying that "as friends we will continue to support our four children in the years ahead."

Marina has thrown her husband out twice before — first in 2004 over his four-year affair with writer Petronella Wyatt, and then again in 2010 when he was suspected of having a lovechild with art consultant Helen ­Macintyre.

On both occasions, Marina has taken him back, but this time Boris seems to have gone too far.
